[fix] charts: no intersect needed for tooltip
Added intersect: false option to Chart.js charts, because currently we have to place the cursor exactly on the lines to display tooltip, which is quite hard and not convenient.
Gitlab was upgraded to latest version (v18.3.1), please report issues to https://forum.duniter.org/t/interventions-et-indisponibilite-des-forums-et-de-gitlab/7131/298
